Article processing charges
Readers never pay to access RDPub journals. The Journal of Digital Intelligence and Knowledge Discovery (JDIKD) charges no article processing charge. The International Journal of Theoretical & Applied Computational Intelligence (IJTACI) charges none for manuscripts submitted before 1 January 2028; from that date an APC of US$250 applies to accepted articles, with waivers based on the Research4Life country groups.
